I go hunting for swirls all the time, especially in multi storeys, and I saw a Mini the other day covered in buffer trails in the sunshine. I wanted so badly to go over and tell the owner that her car looked a state but thought I'd come across as a bit of a maniac.
As for wax, mine is currently 'wearing' a layer of Dodo Juice Light Fantastic topped with a layer of Supernatural. I have to say, the Supernatural definitely adds a certain something to the finish that I haven't been able to get with other waxes, and it beads and sheets superbly too. It looks weird when washing the car, most of the water just falls off.
